    Not sure where to post this, please move if in the wrong place.

    I was wondering if there is anything I can do, or if there is a problem concerning my gas mileage. It seems I do not get much out of a tank of gas. I drive a lot of highway miles but it still seems my gas goes way too quickly. Any ideas/suggestions???

    Miles on full tank divided by gallons used @ fillup. Run three or four tanks and tell us what your MPG is and what your car is.
    That hleps in figuring out what up.

    Since your car appears new to you, and since winter gas is probably being used most places now, it takes a little time to figure baseline and trends.

    According to my DIC my estimated MPG are, hwy 28-30 city 23-25. it varies depending on the traffic, if I have get too many red lights of course is going down, if on the hwy a slow driver make me slow down then accelerate again it affects MPG. How accurate is that? I think is very accurate because I drove 25 miles from the hospital to my house and my DIC said I used 1 gallon, so 25 miles drove and 1 gallon used and my DIC showed 25.5... good right? lol
